ABSTRACT:
An electrophotographic copying process employs a photosensitive member which includes a conductive layer carrying a sequential lamination of a photoconductive layer which is sensitive to visible light and a function layer different therefrom, forms an electrostatic latent image by trapping charge on opposite sides of either of the photoconductive layer and the function layer in such a condition that a layer which is not retaining the charge is one of photoconductive layers forming the photosensitive member, and repeatedly employs the electrostatic latent image to produce a plurality of copies. During the copying step for producing a plurality of copies, a uniform exposure by light rays which activate the one of photosensitive layers forming the photosensitive member which is not retaining the charge is applied to the photosensitive member.
